Chosen Theme: Insulating Your Home for Maximum Efficiency
How Heat Moves—and How Insulation Stops It
Conduction, convection, and radiation in your walls
Conduction sneaks heat through solid materials, convection rides along with air movement, and radiation beams energy across spaces. Effective insulation reduces conduction, air sealing tames convection, and reflective surfaces limit radiation, working together to keep conditions steady.
R-value, U-factor, and diminishing returns explained
R-value measures resistance to heat flow, while U-factor measures the opposite. Higher R and lower U are better, but returns diminish if air leaks and moisture persist. Pair insulation with air sealing for meaningful, lasting gains.
A winter draft that sparked a comfort breakthrough
One icy January evening, a sly draft crept under our baseboard and chilled the whole room. After sealing rim joists and adding attic insulation, the space felt instantly calmer. Share your draft detective stories below.
Choosing the Right Insulation Material
01
Fiberglass and mineral wool: reliable, accessible workhorses
Fiberglass and mineral wool are widely available, budget-friendly choices with solid R-values and fire resistance. They perform best when carefully fitted, with full cavity coverage and minimal gaps. Pair with diligent air sealing for dependable results.
02
Cellulose: recycled content with dense-pack advantages
Blown or dense-pack cellulose uses recycled paper treated for fire resistance, delivering great coverage and sound dampening. Dense-pack methods reduce air movement within cavities, improving comfort. Ask your installer about settling control and verified density.
03
Spray foam: air sealing and structure in one application
Closed-cell spray foam adds high R per inch and robust air sealing, even strengthening assemblies. Open-cell is lighter and great for sound control. Plan carefully around wiring, ventilation, and moisture management to avoid unintended consequences later.
Where Insulation Matters Most
Hot air rises, making attics a crucial upgrade zone. Add proper depth, ensure even coverage, and protect ventilation paths at eaves. Air seal can lights, chases, and penetrations before insulating for a dramatic comfort and cost difference.
Where Insulation Matters Most
For existing homes, dense-pack cellulose can boost wall performance without major demolition. In new builds, use continuous exterior insulation to cut thermal bridging. Always confirm vapor control strategy suits your local climate conditions and wall assembly.
Where Insulation Matters Most
Start with water management: gutters, grading, and vapor barriers. In conditioned basements, rigid foam against concrete helps prevent condensation. Crawl spaces benefit from sealing, ground membranes, and perimeter insulation, turning damp energy drains into stable, useful spaces.
Air Sealing, Moisture, and Ventilation
A blower door test pressurizes the house so leaks become visible. Use smoke pencils to identify gaps at outlets, attic hatches, and rim joists. Seal with caulk, tape, and gaskets for measurable efficiency improvements and quieter rooms.
DIY safety and prep checklist that saves headaches
Wear proper PPE, protect wiring, maintain clearances around recessed lights and flues, and label junction boxes. Stage materials, cover flooring, and photograph assemblies before closing cavities. Careful prep keeps projects smooth and results consistent.
When a professional crew earns its keep
Pros shine with dense-pack cellulose, spray foam, and complicated rooflines. They can handle blower door verification, rebates, and warranties. Ask for references and test results. Tell us what you plan, and we’ll help refine the scope.
Track results and celebrate your comfort gains
Compare utility bills year over year, take infrared images, and keep a comfort journal noting drafts, noise, and humidity. Post your before-and-after stories, and subscribe for our checklist on verifying insulation performance with easy home tools.
